Bollard
A bollard is a sturdy, short, vertical post. The term originally referred to a post on a ship or quay used principally for mooring boats. It now also refers to posts installed to control road traffic and posts designed to prevent automotive vehicles from colliding or crashing into pedestrians and structures, whether intentional from ram-raids and vehicle-ramming attacks, or unintentional losses of control. Etymology The term is probably related to bole, meaning a tree trunk. The earliest citation given by the ''Oxford English Dictionary'' (referring to a maritime bollard) dates from 1844, although a reference in the ''Caledonian Mercury'' in 1817 describes bollards as huge posts. History Wooden posts were used for basic traffic management from at least the beginning of the 18th century. An early well-documented case is that of the "two oak-posts" set up next to the medieval Eleanor cross at Waltham Cross, Hertfordshire, in 1721, at the expense of the Society of Antiqua ...

Vehicle-ramming Attack
A vehicle-ramming attack is an assault in which a perpetrator deliberately rams a vehicle into a building, crowd of people, or another vehicle. According to Stratfor Global Intelligence analysts, this attack represents a relatively new militant tactic that could prove more difficult to prevent than suicide bombings. Deliberate vehicle-ramming into a crowd of people is a tactic used by terrorists, becoming a major terrorist tactic in the 2010s because it requires little skill to perpetrate, cars and trucks are widely available, and it has the potential to cause significant casualties. Deliberate vehicle-ramming has also been carried out in the course of other types of crimes, including road rage incidents. Deliberate vehicle-ramming incidents have also sometimes been ascribed to the driver's psychiatric disorder.Alan R. Felthouse,Personal Violence in ''The American Psychiatric Publishing Textbook of Forensic Psychiatry'' (2d ed.: eds. Robert I. Simon & Liza H. Gold), pp. 551-52 ...

Overspill Parking
Overspill parking is the parking of vehicles beyond a defined area specifically designed for this purpose. It can occur because provided parking spaces are insufficient for demand or considered unsatisfactory, and may have unintended consequences on its surroundings. Additional official parking may be provided for an event, or at some distance from the intended destination. Overspill car parking may simply be parking further away from a place than desirable. In some circumstances it may involve parking violations or other unauthorised or anti-social parking such as double parking, parking on verges or on sidewalks and can on occasions create difficulties for others. Available parking may be insufficient, unsuitable, expensive or otherwise undesirable. Parking may be limited because the urban form historically made little provision for the parking of private vehicles, or because the transport authority zoning policies consciously limit the provision of parking spaces to discourage ...

Bitts
Bitts are paired vertical wooden or metal posts mounted either aboard a ship or on a wharf, pier or quay. The posts are used to secure mooring lines, ropes, hawsers, or cables. Bitts aboard wooden sailing ships (sometime called cable-bitts) were large vertical timbers mortised into the keel and used as the anchor cable attachment point. Bitts are carefully manufactured and maintained to avoid any sharp edges that might chafe and weaken the mooring lines. Use Mooring lines may be laid around the bitts either singly or in a figure-8 pattern with the friction against tension increasing with each successive turn. As a verb ''bitt'' means to take another turn increasing the friction to slow or adjust a mooring ship's relative movement. Mooring fixtures of similar purpose: * A bollard is a single vertical post useful to receive a spliced Spliced may refer to: *Spliced, the result of rope splicing Rope splicing in ropework is the forming of a semi-permanent joint between two r ...

Street Furniture
Street furniture is a collective term for objects and pieces of equipment installed along streets and roads for various purposes. It includes benches, traffic barriers, bollards, post boxes, phone boxes, streetlamps, traffic lights, traffic signs, bus stops, tram stops, taxi stands, public lavatories, fountains, watering troughs, memorials, public sculptures, and waste receptacles. Description and use Street furniture is a collective term used in the United States, United Kingdom, Australia, and Canada. It refers to objects and pieces of equipment installed along streets and roads for various purposes. The design and placement of furniture should take into account aesthetics, visual identity, function, pedestrian mobility and road safety. For example, street furniture can be positioned to control overspill parking in addition to its primary purpose; for example a bench and a number of bollards may be used to block access to a sidewalk or verges for vehicles.

Sidewalks
A sidewalk (North American English), pavement (British English), footpath in Australia, India, New Zealand and Ireland, or footway, is a path along the side of a street, highway, terminals. Usually constructed of concrete, pavers, brick, stone, or asphalt, it is designed for pedestrians. A sidewalk is normally higher than the roadway, and separated from it by a kerb (spelled "curb" in North America). There may also be a planted strip between the sidewalk and the roadway and between the roadway and the adjacent land. In some places, the same term may also be used for a paved path, trail or footpath that is not next to a road, for example, a path through a park. Terminology The term "sidewalk" is preferred in most of North America. The term "pavement" is more common in the United Kingdom and other members of the Commonwealth of Nations, as well as parts of the Mid-Atlantic United States such as Philadelphia and parts of New Jersey. Many Commonwealth countries use the term "f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wharf
A wharf, quay (, also ), staith, or staithe is a structure on the shore of a harbour or on the bank of a river or canal where ships may dock to load and unload cargo or passengers. Such a structure includes one or more berths (mooring locations), and may also include piers, warehouses, or other facilities necessary for handling the ships. Wharves are often considered to be a series of docks at which boats are stationed. Overview A wharf commonly comprises a fixed platform, often on pilings. Commercial ports may have warehouses that serve as interim storage: where it is sufficient a single wharf with a single berth constructed along the land adjacent to the water is normally used; where there is a need for more capacity multiple wharves, or perhaps a single large wharf with multiple berths, will instead be constructed, sometimes projecting over the water. A pier, raised over the water rather than within it, is commonly used for cases where the weight or volume of cargos will b ...

Ram-raid
Ram-raiding is a type of burglary in which a heavy vehicle is driven into the windows or doors of a building, usually a department store or jeweller's shop, to allow the perpetrators to loot it. Overview The term came into widespread use after a series of such raids in Belfast, Northern Ireland, in 1979 that was covered in news reports and in countries such as Australia that inspired a series of similar crimes. Notably, large trucks are used to break into technology companies and steal high-value equipment for resale on the black market. Commercial properties in areas prone to ram-raids often erect barriers or obstructions, such as bollards, to discourage such attacks. Automated teller machines are also targets of ram-raiding, with criminals smashing the machines to steal cash boxes. Many companies have come up with solutions to ram-raiding.

Street Light
A street light, light pole, lamp pole, lamppost, street lamp, light standard, or lamp standard is a raised source of light on the edge of a road or path. Similar lights may be found on a railway platform. When urban electric power distribution became ubiquitous in developed countries in the 20th century, lights for urban streets followed, or sometimes led. Many lamps have light-sensitive photocells that activate the lamp automatically when needed, at times when there is little-to-no ambient light, such as at dusk, dawn, or at the onset of dark weather conditions. This function in older lighting systems could be performed with the aid of a solar dial. Many street light systems are being connected underground instead of wiring from one utility post to another. Street lights are an important source of public security lighting intended to reduce crime. History Preindustrial era Early lamps were used by Greek and Roman civilizations, where light primarily served the purpose of ...

Intersection (road)
An intersection or an at-grade junction is a junction where two or more roads converge, diverge, meet or cross at the same height, as opposed to an interchange, which uses bridges or tunnels to separate different roads. Major intersections are often delineated by gores and may be classified by road segments, traffic controls and lane design. Types Road segments One way to classify intersections is by the number of road segments (arms) that are involved. * A three-way intersection is a junction between three road segments (arms): a T junction when two arms form one road, or a Y junction, the latter also known as a fork if approached from the stem of the Y. * A four-way intersection, or crossroads, usually involves a crossing over of two streets or roads. In areas where there are blocks and in some other cases, the crossing streets or roads are perpendicular to each other. However, two roads may cross at a different angle. In a few cases, the junction of two road segments ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
